Week 8 quiz

Question 1
1 out of 1 points
A 34-year-old male has been diagnosed with TB and will be started on INH therapy. The medication
history reveals that he currently takes antacids on a regular basis. The nurse will instruct the patient
to take
Response The patient should take antacids not less than 1 hour before or 2 hours after
Feedback: taking INH. INH should not be taken with meals unless the patient has gastrointestinal
distress. It does not matter when INH or the antacid is taken during the day as long as
the time frame is appropriate.
Question 2
1 out of 1 points
A 30-year-old woman who is in the first trimester of pregnancy has presented to her primary care
provider with a 4-day history of a reddened, itchy left eye that is crusted with purulent exudate. The
clinician suspects a bacterial, rather than viral, etiology. How will the patient's pregnancy affect the
potential use of ciprofloxacin to treat her conjunctivitis?
Response Ciprofloxacin is contraindicated in patients who are pregnant or lactating.
Feedback: Alternative routes and dosages do not mitigate the risks during pregnancy.
Question 3
1 out of 1 points
A 72-year-old patient is prescribed ophthalmic ciprofloxacin for a bacterial infection in her right eye.
The nurse will teach her to observe for which of the following adverse effects of the drug?
Response Adverse reactions to ophthalmic ciprofloxacin usually involve local effects such
Feedback: as burning or discomfort. Other adverse effects of ophthalmic ciprofloxacin are lid margin
crusting, crystals, scales, foreign body sensation, pruritus, conjunctival hyperemia, and
a bad taste in the mouth. Increased intracranial pressure and tendon ruptures are not
identified adverse effects of ophthalmic ciprofloxacin. Nephrotoxicity and
neurotoxicity are the primary adverse effects of polymyxin B.
Question 4
1 out of 1 points
An immunocompromised patient in a critical care setting has developed a respiratory infection that
has been attributed to methicillin-resistant Staphylococcus aureus (MRSA). The nurse should
anticipate that the patient will require treatment with

, Response Vancomycin is the drug of choice to manage infections caused by MRSA.
Feedback: MRSA is resistant to all of the antistaphylococcic penicillins, as well as to
ciprofloxacin and clindamycin.
Question 5
1 out of 1 points
A 46-year-old man is receiving a quinupristin/dalfopristin IV infusion for a life-threatening infection.
Which of the following would be most important for the nurse to monitor?
Response During quinupristin/dalfopristin infusion, the nurse should monitor the IV site for
Feedback: signs of infiltration, edema, or phlebitis. The nurse should also question the patient about
pain at the injection site. Quinupristin/dalfopristin is not known to affect heart rate or
cause breathlessness. Nausea and vomiting have not been identified as common
adverse effects of quinupristin/dalfopristin infusion.
Question 6
1 out of 1 points
An immunocompromised patient with a diagnosis of candidiasis has failed to respond to
conservative therapy and has consequently begun treatment with amphotericin B. The nurse is
aware that this drug achieves a therapeutic effect by way of its influence on
Response Amphotericin B works by binding to sterols in fungal cell membranes. This
Feedback: binding appears to form pores or channels and results in increased cell permeability, cell
leakage, and death. The drug does not influence human immune function, fungal
reproduction, or the osmolarity within fungal cells.
Question 7
1 out of 1 points
A nurse has questioned why a patient's physician has prescribed a narrow-spectrum antibiotic rather
than a broad-spectrum drug in the treatment of a patient's infection. Which of the following facts
provides the best rationale for the use of narrow-spectrum antibiotics whenever possible?
Response The benefit of a narrow-spectrum antimicrobial agent is that it limits the Feedback:
potential for adverse effects, such as superinfection. In a superinfection, an
antibiotic suppresses all susceptible microbes, including the body's natural flora,
which may keep other microbes in check. In the absence of these bacteria,
nonsusceptible microbes can proliferate. Narrow-spectrum antibiotics do not lack
demonstrated efficacy and they do not necessarily require a shorter duration of
treatment. All antimicrobial drugs have the potential to impact subsequent C&S
testing.
